Overall, though, it's a good service. Check this out: it's a graph of a garden that in theory provides enough veg for a family of two for a year, provided you're also canning and freezing. The way it's going to be good for me is that it gives me an idea of when to plant things. Obviously my garden isn't 25'x42', so I'll need to scale this down. But how cool that they've given home veg gardeners an actual example garden layout??

From here. NB: this is for the lower Piedmont and Upper Coastal Plain areas of NC.
